Change of the tones by external control
For applications which require more tones than just the base tone, it is possible to provide up to three additional
tone types with the use of the following electrical controls.
As a basic rule, the desired base tone (♪, see tone table in the appendix) is set with the tone selector switch S3 on
the driver board. The corresponding additional tones (C1, C2, C1+C2) can be gathered from the table "Selection of
the tones".
Tone selection with control input (TAS)
DC-Version:
When used with correct polarity, the tone selection
takes place through the control inputs C1 and C2 on
the circuit board. In the process, the supply voltage
must always be applied together with the two control
inputs. Switch S1 on the driver board is open.
The selection of the polarity of the control voltage
("+" or "-") takes place with the switch S2 on the driv-
er board.
"+": positive control
"-": negative control (factory setting)
Caution: If the control voltage is greater than the
supply voltage or the supply voltage is not applied,
the operating current supply is provided through the
control inputs. A corresponding load capacity must
then be guaranteed.
AC-version:
In the AC version the tone selection takes place by
connecting the phase "L" of the supply voltage to the
control inputs C1 and C2. In the process, the supply
voltage must always be applied together with the two
control inputs.
Tone selection with supply through control input (TAV) - for all DC versions
The sounder can be supplied with operating voltage through the control inputs C1 and C2 on the circuit board.
Supply and tone selection thus take place simultaneously.
The minus pole of the sounder must be connected. With connection of the positive voltage to the plus pole of the
circuit board, the base tone (♪) is generated; with connection to C1 or C2 the corresponding tone is selected.
With simultaneous connection of the positive voltage to C1 and C2 the tone "C1+C2" is selected.
The switch S2 on the driver board must be set to "+".

Tone selection through pole reversal (TAR) - for all DC versions
If the switch S1 on the driver board is closed, the tone "C1+C2" can be selected in addition to the base tone
through pole reversal. The switch S2 must be set to "+".
The control inputs C1 and C2 may not be switched on the circuit board.
